Spell check commit messages

[TomSeldon]

Not sure how practical this will be, but seems like it would be useful to check the spelling in commit messages.

On the surface it seems straightforward enough, after all there are existing NPM modules available to handle spell-checking. However, the perceived difficulty will come with words that we want to accept, but aren't necessarily correct English (e.g. project names, technical terms, etc.).

I'm not sure there's an easy way of handling that, other than maintaining a whitelist of words (in addition to using standard dictionary). That dictionary may need to change dependent on project, which adds in a level of configurability that just doesn't exist right now.

Open to ideas / suggestions.
